How to get access to my camera from my app in Android

Question

I am creating a app. In this application I want to open my camera and I want to save it.

So I wrote code to do that

takepic.setOnClickListener(new View.OnClickListener() {

        @Override

        public void onClick(View v) {

            count++;
            String file = dir+count+".jpg";
            File newfile = new File(file);

            try {
                newfile.createNewFile();
            }
            catch (IOException e)
            {

            }

            Uri outputFileUri = Uri.fromFile(newfile);

            Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);

            startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);

        }
    });

and also i have added the permission to the manifest file

<?xml version="1.0" encoding="utf-8"?>

<uses-feature android:name="android.hardware.camera"
    android:required="true" />


<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/app_id" />

    <activity android:name=".LoginActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.facebook.FacebookActivity"
        android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Translucent.NoTitleBar" />
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main"
        android:theme="@style/AppTheme.NoActionBar"></activity>
</application>

But when I try to open the camera I am getting this error:

java.lang.SecurityException: Permission Denial:

Why am I getting this since I have added the permissions

This is my error in the log

If your compileSdkVersion is less than 23, below marshmallow, you only need to define following permission in Manifest:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

If you are saving the image or video then define the WRITE_EXTERNAL_STORAGE permission also.

Now for marshmallow you have to define permission dynamically ,something like this:

    private static final int REQUEST_CAMERARESULT=201;

ibtn_cam.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                if(getActivity().checkSelfPermission(Manifest.permission.CAMERA)== PackageManager.PERMISSION_GRANTED){
                    ///method to get Images
                    takeVideo();
                }else{
                    if(shouldShowRequestPermissionRationale(Manifest.permission.CAMERA)){
                        Toast.makeText(getActivity(),"Your Permission is needed to get access the camera",Toast.LENGTH_LONG).show();
                    }
                    requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CAMERA}, REQUEST_CAMERARESULT);
                }
            }else{
                takeVideo();
            }
        }
    });

In place of takeVideo u can use any method to open the camera, i have used

public void takeVideo(){
    Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);

    fileUri = getOutputMediaFileUri(MEDIA_TYPE_VIDEO);

    // set video quality
    // 1- for high quality video
    intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
    // start the video capture Intent
    getParentFragment().startActivityForResult(intent, CAMERA_CAPTURE_VIDEO_REQUEST_CODE);

    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(fileUri.getPath());
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    sendBroadcast(mediaScanIntent);

}

To save the video to gallery you have to use a new intent with sendBroadcast(mediaScanIntent) as shown above

if you are writing all this code inside feagment don't forgot to use context to call sendBroadcast(mediaScanIntent) as getActivity().sendBroadcast(mediaScanIntent)
